2 Safety
All warnings in this manual are summarised on this page.
Pay special attention to this instructions below so that severe personal injury and/or damage to the valve are avoided.
2.3 Safety precautions
Actuators marked with year 2012 (new actuator
design):
Alfa Laval recommends not to exceed 3 bar support air
onthespringsideinalltheUniqueSSVactuators,to
ensure 10 bar product pressure without leakage. Alfa Laval recommends max. 3 bar
Plastic adapter (pos. 5) is always used on the new
design.
ø157.5 mm

Actuators marked with year 2006-2011 (old actuator
design):
WARNING! Max. 3 bar “support air” on spring side.
When using “support air” on spring side in all the Unique
SSV actuators, the pressure must NOT exceed 3 bar.
When using Unique SSV actuators with ø156mm with
support air, always use the “steel adapter” (pos. 5).
Tighten the “steel adapter” to a torque of 30 Nm and
use Loctite 243.
ø156 mm
The actuator with ø156mm is mainly used on valves
ISO76/DN80 – ISO101/DN100. The outer actuator
diameter = ø156 mm.
